Working Principles

The AD7896ARZ operates based on the successive approximation register (SAR) architecture. It samples the analog input voltage, compares it to a reference voltage, and generates a digital output representing the converted value. The internal circuitry performs a series of binary comparisons to determine the most significant bits first, followed by the less significant bits.
